The yogurt shop murders DNA evidence that overturned the convictions of 4 men wrongfully accused
Quick Read
Summary
Takeaways
- ❖The 1991 'I Can't Believe It's Yogurt!' shop murders in Austin involved four teenage girls (Jennifer and Sarah Harbison, Eliza Thomas, Amy Ays) who were gagged, tied, shot, and the shop set on fire.
- ❖Initial investigations were extensive but yielded no arrests, with lead investigator Jon Jones noting six separate false confessions during his tenure.
- ❖Eight years after the murders, four men (Maurice Pierce, Forest Wellborn, Michael Scott, Robert Springsteen) were arrested, having been previously questioned and released shortly after the crime.
- ❖The new arrests were primarily based on two confessions obtained from Michael Scott and Robert Springsteen, which their defense attorneys argued were coerced.
- ❖Robert Springsteen was convicted of capital murder and sentenced to death; Michael Scott was convicted and sentenced to life in prison.
- ❖Both convictions were later overturned by the Supreme Court on Sixth Amendment grounds, as their confessions were used against each other without the opportunity for cross-examination.
- ❖Subsequent YSTR DNA testing on vaginal swabs from a sexually assaulted victim yielded a partial male DNA profile that conclusively did not match any of the four accused men.
- ❖Despite a promising hit on a public DNA database in 2017, further advanced testing in 2020 revealed that the FBI sample did not match the crime scene DNA, leaving the identity of the DNA donor unknown.
- ❖The case remains unsolved, with the DNA profile being the most critical piece of evidence, offering hope for future resolution as forensic technology advances.

1The Brutality and Initial Investigation of the Yogurt Shop Murders
On December 6, 1991, four teenage girls—Jennifer Harbison (17), Sarah Harbison (15), Eliza Thomas (17), and Amy Ays (13)—were murdered at an 'I Can't Believe It's Yogurt!' shop in Austin. They were gagged, tied with their own clothing, shot in the head, and at least one victim was sexually assaulted. The shop was then set on fire, destroying potential evidence. Investigators quickly determined two different types of guns (a .380 and a .22) were used, suggesting at least two killers. The crime shocked Austin, and lead investigator Jon Jones coordinated efforts with multiple agencies, tracking hundreds of suspects.
Jon Jones, the lead investigator, described the scene as 'indelibly burned in my mind' and the crime as 'the most grisly, ugly crime' in Austin's history. Two different gun calibers (.380 and .22) were identified from gunshot wounds, indicating multiple perpetrators. The fire destroyed fingerprint evidence. (, , , , , , )
2The Unreliable Nature of Confessions: Six False Admissions
Throughout the initial investigation, police received numerous confessions that proved to be false. Lead investigator Jon Jones stated that his team faced 'six confessions'—written admissions to the crime—all of which were determined to be untrue. This pattern foreshadowed later issues with confessions in the case.
Jon Jones explicitly stated, 'You know, we've faced six confessions.' When asked if these six people confessed to the crime and didn't do it, he confirmed, 'Yes, they did. Nope.' (, )
3Wrongful Convictions Based on Coerced Confessions
In 1999, eight years after the murders, four men (Maurice Pierce, Forest Wellborn, Michael Scott, and Robert Springsteen) were arrested, having been initial suspects who were released. The new arrests were primarily based on confessions obtained from Michael Scott and Robert Springsteen after intense, multi-day interrogations. Both men later claimed their confessions were coerced, with Springsteen stating he was 'badgered and badgered' until he told police 'any damn thing you want.'
Defense attorney Joe James Sawyer stated, 'The only thing that ever tied Robert or Mike Scott to that crime scene were their confessions.' Springsteen explained to 48 Hours, 'I was badgered and badgered and badgered by the police officers until they obtained what it was they wanted to hear. They were not going to allow me to leave. And I I basically they they broke me down.' (, , )
4Constitutional Rights Violations Lead to Overturned Convictions
Robert Springsteen and Michael Scott were convicted in 2001 and 2002, respectively, with Springsteen sentenced to death and Scott to life. However, their convictions were overturned in 2006-2007 by the Supreme Court. The court ruled that their Sixth Amendment rights to confront accusers were violated because their confessions were used against each other in separate trials, but they were not allowed to cross-examine each other in court.
A news report stated, 'In a 5-4 decision, the court behind me said that Michael Scott's constitutional rights were violated during his trial and therefore should get a new one.' The explanation cited the Sixth Amendment right to confront accusers, noting that 'their confessions were used against one another, but they weren't allowed to question each other in court.' (, )
5DNA Evidence Exonerates the Accused, Reveals New Suspect
Following the overturned convictions, a new district attorney ordered YSTR DNA tests on vaginal swabs from one of the victims. This technology, which searches for male DNA, yielded a partial male DNA profile. Crucially, this DNA did not match any of the four original suspects, including Scott and Springsteen. This finding directly contradicted Springsteen's coerced confession where he claimed to have raped one of the girls, effectively exonerating the accused and indicating an unknown perpetrator.
DA Rosemary Lmberg confirmed, 'A partial male DNA profile was obtained from one of the victims believed to have been sexually assaulted... It does not [match any of the four young men].' DNA expert CC Moore explained that if YSTR DNA does not match, 'they did not contribute that' where the DNA was found. (, , )
6The Elusive DNA Match: FBI Database Hit and Disappointment
In 2017, an Austin police investigator found a potential match for the YSTR DNA in a public online database. The FBI had anonymously submitted the sample from a federally convicted offender. However, the initial 16-marker profile was not highly detailed. After the FBI eventually agreed to further testing in 2020, more advanced analysis (25 markers) revealed that some additional markers did not match the FBI sample, conclusively excluding that individual as the donor. This dashed hopes for a quick resolution.
An investigator stated, 'Unbelievably, he did [get a hit]. I thought, my god, we actually have a chance, a shot to solve this crime.' However, DNA expert CC Moore noted, '16 STRs is not a very powerful match. There could be millions of people with that same profile.' The FBI's letter to Congressman McCall 'conclusively exclude the male donor of the FBI sample.' (, , , )
Lessons
- Law enforcement agencies must implement rigorous protocols to prevent coerced confessions, as they can lead to wrongful convictions and divert resources from finding true perpetrators.
- Legal systems should prioritize and continually invest in advanced forensic technologies like DNA analysis, as they are crucial for accurate identification and exoneration in criminal cases.
- Victim support services should acknowledge the long-term psychological impact of unsolved crimes, providing ongoing resources for families dealing with prolonged grief, trauma, and lack of closure.
